How to integrate a form in a sharepoint upload process:
We are currently building a sharepoint (we use Sharepoint Online) for the exchange of internal documents. So that the users can search in the Sharepoint as specifically as possible, those who upload the documents should fill out a form in which they add important information to the document (properties). This form should appear at the beginning of the upload process and the actual upload should only take place after completing the form. Then we want to use approval workflows that get triggered only after all mandatory metadata (properties) of an uploaded document have been assigned. Does anyone have any experience of how such a form can be created and inserted into the upload process?
